STEAM-CONDENSER AND OlL-SEPARATOR.

SPECIFICATION forming part Of Letters Patent N0. 538,600, dated. April 30, 1895.

Application filed June 13, 1894- Serial No. 514,402. (No model.)

To etZZ whom it may concern:

Be it known that I, EDWARD ROWE, of Indiana, in the county of Indiana and State of Pennsylvania, have invented a new and Improved Steam-Condenser and Oil-Separator, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved steam condenser and oil separator, which is comparatively simple and durable in construction, very effective in operation, and more especially designed for condensing exhaust steam from engines or other apparatus, and to return the water of condensation to the feed pump or other device, at the same time purifying the water to prevent incrustation of the boiler.

The invention consists principally in a series of connected vessels, of which the first receives the steam, and each vessel is provided with air tubes for the circulation of air, to condense the steam circulating in the vessel.

The invention also consists in certain parts and details, and combinations of the same, as will be hereinafter fully described and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement with parts in section. Fig. 2 is an enlarged sectional plan view of one of the con- (lensing-vessels on the line 2 2 of Fig. 3. Fig. 3

is a transverse section of the same on the line 3' 3 of Fig. 2. Fig. 4 is an enlarged sectional plan view of two air-tubes with a baffie-plate between them, and Fig. 5 is a side elevation of a modified form of the improvement.

The improved condenser as illustrated in Figs. 1 to 4 receives the steam from an engine A, orother apparatus, by means of an exhaust pipe B extending upwardly and provided at its upper end with two or more branch pipes B, discharging into the upper end of a condensing vessel 0, preferably made circular in form and resting on beams D, set on a floorE This condensing vessel 0 is provided with a series of vertically disposed air tubes F, passing through the heads of the condensing vessel C, to permit air to freely circulate through the said tubes.

Between adjacent air tubes F are held battle plates G, G, arranged in such a manner that one outer set G, of the baffle plates, as illustrated in Fig. 2, extends from the upper head of the vessel 0 to within a short distance of the lower head, while the inner set of battle plates Gflextends from the bottom head upwardly to within a short distance of the upper head of the said condensing vessel. See Fig. 3. By this arrangement, the steam entering the branch pipes B at the top of the vessel 0, is first forced to pass downward between the shell of the condensing vessel and the first set of battle plates G, and then the steam passes between the two sets of battle plates G and G, to finally pass into themiddle portion of the condenser, and downward to the lower end of a pipe H, extending through the upper head of the condensing vessel to within a short distance of the bottom thereof, as, plainly indicated in Fig. 3. The steam now passes up this pipe H, and out of the condensing vessel 0.

The outer end of the pipe H is bent downward to connect by branch pipes H with a second condensing vessel I, similar in construction to the vessel 0, and also provided with a steam outlet pipe H connected by branch pipes H with a third condensing vessel 1, similar to'the vessels I and O. The outlet pipe H of this vessel 1' may connect with a fourth condensing vessel, or mayopen into the outer air.

In the lower head or bottom of each vessel 0, I or I, are arranged water outlet pipes J, J or J discharging into a common pipe J extending to within a short distance of the bottom of a grease tank K, in which thewater of condensation accumulates, and from which grease or other impurities may be skimmed off from time to time. From the bottom of this tank K leads a water outlet pipe L, provided with a valve L, and connected with a feed pump N or other device for returning the water to the boiler or other apparatus. An air pipe L in the upper end of the pipeL prevents siphoning of water from the grease tank K, by the pipe L.

It will be seen that when the air circulates through the air tubes F and the steam circulates in each condensing vessel around the said air tubes, then the steam readily condenses, and the water of condensation flows through the water outlet pipe J, J or J to the grease tank K, in which it accumulates. As the condensing vessels 0, I and I are comparatively large, the steam can readily pass through the same without creating back pressure. It will further be understood that by the arrangement described,no water jackets or other water circulating devices are necessary to condense the steam, it being understood that the condensing is brought about by circulating air through the air tubes in th condensing vessels.

In the apparatus shown in Fig. 5, the exhaust steam from the engine or other apparatus passes through the pipe 13 into and through a condensing vessel 0' similar in con-- struction to the vessel Oabove described and illustrated in Figs. 1, 2 and 3. The steam outlet pipe 1-1 of this condensing vessel 0' connects with the upper end of the condensing vessel 1 made comparatively high and of a small diameter, with air pipes passing through the vessel and its heads to permit a circulation of air through the pipes to condense the steam passing through the vessel 1 The latter is connected at or near its bottom by a branch pipe 11 with a second vessel 1 similar to the vessel 1 and connected at its upper end by abranch pipe H with the upper end of another condensing vessel 1 connected at its lower end, by the branch pipe H with a condensing vessel 1 provided at its upper end with an outlet pipe H for vapors not condensed. The several vessels I I and I are all similar in construction to the vessel I and their bottoms are connected by pipes J J J and J with a pipe J leading to an oil separator similar to the one above described and shown in Fig. 1. A pipe J connectsthe vessel G with the pipe J and thispipe J as well as the pipes J J J and J serves to carry the water of condensation for the vessels 0', 1 I I and I to the oil separator. It is understood that any desired number of such vessels 1 I I and I may be connected with each other alternately at the top and bottom as described. The air passing through the air pipes in the said vessels causes a condensation of the steam passing through the vessels, and the water of condensation passes through the water outlet pipes to the oil separator.

As the impurities of the water of condensation can readily be skimmed ed in the grease tank K, the water passed to the feed pump is in a pure state,and consequently incrustation of the boiler is prevented.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A steam condenser and oil separator, comprising a vessel provided with a series of air tubes passing through the heads thereof and opening into the outer air, and with a series of battle plates between adjacent air tubes,

and forming concentric sets of bathe plates extending from the upper and lower heads respectively of the vessel, an exhaust pipe leading into the upper part of said vessel, a tank below the vessel, and a pipe leading from the vessel and projecting into the tank, substantially as described.

2. A steam condenser and oil separator, comprising a vessel provided with a series ofi air tubes passing through the heads of the vessel and opening into the outer air, a series of batfie plates between adjacent air tubes and forming two concentric sets of battle plates extending respectively from the upper and lower heads of the vessel, and an outlet pipe leading out through the upper head, an exhaust pipe leading into the upper part of the vessel, a tank below the vessel, a pipe leading from the vessel and projecting into the tank,.and a pipe leading from the bottom of the tank for connection with a feed pump, substantially as described.

3. A steam condenser and oil separator, comprising a series of vessels connected together at the top and each provided with a series of air tubes passing through the heads thereof and opening into the outer air, a series of baffle plates between adjacent tubes and forming two concentric sets of baffle plateswhich extend respectively from the upper and lower heads of the vessels, and an outlet pipe leading out through the upper head, an exhaust pipe leading into the first vessel of the series, a tank below the said first vessel, outlet pipes leading from the bottoms of the several vessels, and discharging into the said tank, and a pipe leading from the tank for connection with a feed pump, substantially as described.

4. A steam condenser, consisting of a vessel, a series of air tubes passing through the heads of the vessel and opening into the outer air, a series of battle plates between adjacent air tubes and forming concentric sets of baftle plates, the said sets projecting from opposite heads of the vessel and extendingto within a short distance of the head opposite that from which it projects, and a central outlet pipe leading out through the upper head, substantially as described.

5. A steam condenser consisting of the vessel G, the air tubes F arranged in I the vessel and passing through the heads of the vessel, baffle plates G G between adjacent air tubes and arranged in sets, the set G extending from the upper head downward and the set G ex tending from the lower head upward, and the pipe H arranged centrally in the vessel and extending to within a short distance of the lower head, substantially as herein shown and described.
